Title: Additional gauge wiring Post by: lanciamad on December 28, 2014, 03:47:36 PM I've fitted some additional gauges for oil pressure and water temperature, 12v and earth aside, the signal wire for both, can it be spliced off the original wiring to give readings? Or will effectively splitting the wiring to two gauges (as I would like to keep the originals active) cause mayhem?

Title: Re: Additional gauge wiring Post by: lanciamad on December 28, 2014, 06:31:23 PM I would guess that is the case too, perhaps i'll have to fit another union to run two senders

See my post on "sump removal" there is some useful info there. |
